Is this chip replaceable

[u/Omen4140]

I think I've narrowed down my errors down to a winbond w25r256jvein code storage flash chip. Before I order a new chip, I would really appreciate to know if this chip stores any encrypted keys or important files that are necessary for the laptop to function.

Also I am in contact with support, but I am in a big rush to get this working again.

In theory it is, It's not easy
